TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed September 27, 1906. Serial No. 336,512.

To all whom it may concern:

Be it known that I, HARRY C. FERGUSON, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain-new and useful Improvements in Type Writing Machines,of which the following is a specification.

The present invention relates to typewriting machines and moreparticularly to means for readily producing what may be termed linerwork, that is' to say, to means for producing leader or followinglinesin invoice or indexes or for producing lines of stars or underscoringand the like.

To the above and other ends which will hereinafter appear, my inventionconsists .of the features of construction, arrangements of parts andcombinations of devices to be set forth in the following specificationand particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference charactersdesignate corresponding parts in the various views, Figure 1 is aperspective. view as seen from the rear showing one form of typewritingmachine embodying my invention. Fig. 2 is a detail 'top view of theactuating rack or bar and some of the associated parts. Fig. 3 is adetail side elevation partly in section showing the liner type bar andpart of the mech anism designed to actuate it. Fig. 4 is a de; tailperspective view of the type bar actuating wheel and some of theassociated parts. Fig. 5 is a sectional view of the connecting pawl andits support. Fig. 6 is an enlarged fragmentary detail perspective viewshowing a portion of the type actuating wheel and some of the associatedparts.

The present invention relates to anotherconstruction employed for thesame general purposes as the construction of my application No. 394,142in which broader claims are presented, covering the resent invention;the claims of this case being limited to features not embodied in saidapplication No. 394,142.

There are various styles or kinds of typewriters. In some machines thepaper is applied to a carriage which travels while the printinginstrumentalities remain relatively stationary. In other machines theprinting instrumentalities are mounted on a traveling carriage while thepaper holding devices remain relatively stationary. I have elected isdiagrammatically illustrated in Fig. 0.

' to show my invention carried out in the first mentioned kind ofwriting machines but I do not Wish to be confined or limited to amachine of this description, as my invention may be carried out in anyknown style or kind of typewriting machines.

In the accompanyingdrawing, 1 represents the typewriting machine framewhich within itself formsno particular part of the present invention butis illustrated conventionally for the purpose of showing the relation ofthe novel devices of my invention to said frame. Above the top plate ofthe frame 1 ismounted a carriage 2 which may be of any desiredconstruction and' is so mounted that it can be moved back and forthacross the top plate in the usual manner. The carriage has a rotaryplaten which platen with the platen frame and associated parts are notshown in Fig. 1 but are or may be of the usual construction. The platenTo the carriage 2 is attached a toothed bar or rack 3 which moves withthe carriage and is for a purpose to be hereinafter described. To theframe 1 of the typewriting machine is securely attached a bracket 4provided with bearings 5 in which is journaled a shaft 6 having fixedlymounted on the forward end thereof a pinion 7 which meshes with theteeth of the rack 3, the latter rotating said pinion when the carriageis moved in either direction. Upon the shaft (3 is also securely mounteda ratchet wheel Sand adjacent to said ratchet wheel and loosely mountedon the shaftG is a rotary device 9 preferably provided with a series ofinclined teeth, cams or actuating faces 10. A type bar 11 of the usualconstruction is mounted on the frame of the machine and is provided witha type type bar 11 is designed to be actuated by mechanism operated bythe movement of the carriage when the carriage is moved to the right, orto the left, as seen from the rear of the machine as in Fig. 1, the rackbar 3. wheel 9 and intermediate parts above described, being parts ofsuch mechanism.

As a very rapid movement is imparted to top "plate of the machine.

a bracket secured to the base of the machine.

The lever 14 extends-fore and aft of the machine and is pivotally.connected at its forward end to an upright link 15 designed to actuatethe type bar 11 and connected at. its upper end to a crank arm 16connected with the type bar. Y

The angular lever 12 is actuated by a pin 18 carried upon a plate 17which is adjustably secured to the rack 3 by a screw and slotconnection, the connection aflording an adjustment of the plate and pinlengthwise of the rack. This pin is adapted, during the first part ofthe travel of the carriage to the right, to contact with the upper endof the upright arm of the angular lever 12 as shown in Fig. 1 in orderto actuate said angular lever to move it to operative position. Theefiect of this movement of the angular lever is to elevate the link 13,thereby turning the lever 14 against the tension of its spring 36, thusmoving the link 15 down to t e full line position shown inFigQ 3 inorder to effect a preliminary movement of the type bar to bring itadjacent to the printin position as shown in Fig. 3. In order to holdthe angular lever 12 in the position to which it is set by the pin 18 alocking device orarm 20 is provided, said locking device being pivotedto a bracket 21 secured to the The free end of the locking arm isnormally pressed towards the rear of the machine and to the right by aspring 23 which coiiperates'therewith and forces the locking arm into a.notch 22 formed in the upright arm of the angular lever so that theangular-lever is locked in its actuated position against movement tothenormal position. The construction and arrangement of the parts issuch that the locking arm will move into the notch 22 after the angularlever has been moved to the 0perative positionby the pin 18 at or aboutthe beginning of the return movement of the carriage from left to right.When the teeth of the rack 3 come into mesh with the pinion 7 during themovement of the carriage to the right a rotary movement will be impartedto the shaft 6 and this rotary movement of the shaft 6 is transmitted tothe actuating wheel 9 by means of the ratchet wheel 8 and a pawl 19, thelatter being carried by the actuating wheel and pressed by a spring 28into engagement with the teeth of the ratchet wheel ceases parts avibratory movement to a lever 2H pivotally supported between its endsupon an arm or lug 25 which forms part of the bracket 4. pivotallyconnected to a horizontally, dis- )OSQd link 26 provided with an eye atits iorward end through which the link 15 freely passes. By thisarrangement a rotation of the actuatin or cam wheel 9 is ei'icctive tointermittentl y move the u per end of the lever 24. rearwardly and a.low it to spring back, thus imparting a vibratory movement to the link26 fore and aft of the machine, the link 26 being supported near itsforward end in a fixed guide carried by the bracket .4, said guide beinin the nature of a depending wire with a 00p formed at the lower endthereof and through which the link 26 passes. The fore and aft vibrationof the link 26 is efiective to swing the upper end of the link 15transversely from the full to the dotted line position shown in Fig. 3,thus moving the ty e bar 11 from the position shown in full ines to theprinting position indicated in dotted lines in said figure. It should beunderstood that thisrotary movement transmitted through the pawl andratchet to the actuating wheel 9 is effected during the return movementof the carriage or during its movement from left to right. Durin thefeed movement of the carriage from right to left the pinion 7 will berotated but the pawl or detent 19 in this instance will ride over theteeth of the ratchet wheel and no rotary movement will be imparted tothe actuating wheel 9 so that the type bar will remain at rest at thistime.

Iii-case the typewriting machine is to be used in the ordinary mannerand it is desired to throw the line printing type out of operation, itis merely necessary to move the pawl 19 axially on the boss 29 on whichit is pivot.- ed and against the pressure of a spring 3 (Fig. 5). Thismovement. is effective to throw the detent out of cooperation with theratchet teeth of the wheel 8 and it may at this time be allowed to restupon the periphery of the disk 27 as shown in Fig. 6, which disk isadjacent to and may be formed on the forward face of the ratchet wheel.This results in throwing'the actuating wheel 9 out of operation duringthe movement of the carriage in both directions so that no motion willat this time be transmitted to the type bar 11 and it is renderedinoperative. In order that the pawl 19 may be held in either of itsadjusted positions, that is to say, where it cotiperates with the teethof the ratchet wheel or rests on the periphery 27 of the disk, the boss29 .on which the detent is'pivoted is preferably formed integral withthe The lower end of the lever 24-. is

nut and this nut is threaded upon a spindle or post 32 securedto theactuating wheel 9. By rotating the nut 30 in one direction it will bemoved toward the head 31 formed on the post, thereby moving the pawl 19axially against the tension of the spring 33 and towards the periphery27 of the disk and away from the teeth of the ratchet wheel. When it isdesired to bring the pawl into proper engagement with the ratchet wheel8 the engaging end of the pawl is elevated by 'pressure exerted on thetail or end 34 of the pawl and the nut 30 is rotated in a direction 'tomove it away from the head 31, at which. time the spring 33 forces thepawl toward the actuating wheel 19 and into a position where theengaging end of the pawl may engage the teeth of the ratchet wheel.

In order to release the angular lever 12 from locked positionautomatically as the carriage approaches the end of its movement to theright, a block, contact or cam 34: is provided on the rack 3 and may beadjustably secured thereto nection in order to ail rd an adjustment ofthe cam in the direction of the length of the rack 3. During the travelof the carriage to the right the cam 34 is adapted to contact with a lip35 formed on the/locking arm 20 in order to move 'the free end of thelocking arm towards the front of the machine, thus releasing it fromengagement in the notch 22 in the angular lever and the lever is thusautomatically released and it, together with the parts associatedtherewith, may be moved to normal position by the restoring spring 36.

In order to allow the pin 18 to pass the upright arm of the angularlever 12, in the movement of the pin from a position to the right of thelever, the end of said pin is beveled or formed with a cam face aswillbe seen from an ins ction of Fig. 2. As the carriage travels fromright to left the bev eled end of the pin is brought into contact withthe upright arm of the angular lever, deflecting it laterally toward therear of the machine to permit the pin to pass.

resiliency of the lever arm causes it to swin back towards the front ofthe machine an into the path of the pin to be actuated thereby duringthe next movement of the pin to I the carriage is fed from right toleft. During the feed movement of the carriage the rack 3 travelstherewith, turning the pinion 7 andthe ratchet wheel 8 and at this timethe pawl 19 slides freely over the teeth of the ratchet wheel so that nomotion is transmitted to the actuating or cam wheel 9 and 'iio movementis transmitted" to the type bar a screw and slot con- When the pinpasses the upright arm the inherent or carrier ll. During this movementof the carriage the upright arm of the lever 12 is deflected rearwardlyby the pin 18 to allow said pin to pass and springs back into the ,pathof the pin after it has passed. When the carriage reaches the end of theline the pin 18 is in a position slightly to the left of the upright armof the bell crank lever 12 and in a position to actuate-it. As' thecarriage starts to-return to the right the pin 18 turns the lever 12 onits pivot, thus bringing about a movement of the link 13, lever 14 andlink 15 to effect-a movement of the type bar 11 to the full lineposition in Fig. 3 where the type bar is adjacent to the printingposition. The parts are automatically locked in this position by-thelocking device or arm 20 engaging the notch 22 of the angular lever 12.During the movement of the carriage. to the right a rotation istransmitted to the'pinion 7 through the rack 3. The efiect of thisrotation of the pinion 7 is to turn the-actuating wheel 9 through theengag'ementof the pawl 19 with the ratchet wheel 8. The rotation of theactuating-or cam wheel 9 is effective to vibrate the leverv 24, andlinks 26 and 15 to intermittently vibrate the type bar 11 from the fullto the dotted line position shown in Fig. 3, it being understood that anactuation of the type bar 11 is efi'ected at regular intervals in themovement of the carriage, and" an imprint will be effected for eachprinting movement of the bar. hen the cam '34" reaches the projection 35the locking arm 20. will beturned on its pivot, releasing the lever 12and said lever and the parts controlled thereby will be restored totheir normal positions. By adjusting the pin 18 and the cam 34*, thepoints, with reference to the travel of the carriage where the lever 12and the parts controlled thereby are autimatically actuated and releasedfrom their locked positions, may be nicely determined.

'Various changes may be made without departing from the spirit of myinvention,
